WINDOW WEDGE.

Application filed December 17, 1925. Serial No. 78,089.

The present invention relates to improve- I ments in window wedges, an object of the invention being to provide a device of this.

characterwhich will serve the dual purpose of limiting the relative sliding movement of the sashes, and of preventing rattling ofthe sashes when the latter are partially opened. The wedges are equipped with meansv for limiting the relative sliding move ment of the sashes sothat the sashes may be left partially opened without any danger of an intruder gaining entrance through the window. 4

It is a further object of the invention to provide a wedging means which may be conveniently swung to inoperative position to permit. free sliding .movement of the sashes, and a wedging means {which willbe of simple, practical construction, which will be rugged, durable and efiicient inuse, and

which is well suited to the requirements of economical manufacture.

With the above noted and other objects in view, the invention consists in certain 2 novel features of constructionand combinations and arrangement'sof parts, as will be more'fully hereinafter'set forth and pointed out in the. claims. The invention may be more fully understood from the following description in .connection with the accompanying drawings, wherein.

Fig. l'is a plan view of a window frame mounting a pair of sashes and showing my improved wedges in applied position, a portion of the window frame being broken away for the sake of clearness.

Fig. 2 is a sectional detail cut through? the.

channel portion of the window frame and showing the normal position of the sashes.

Fig. 3 is a similar view showing the sashes partially-opened to an extent limited by the Fig. -4 isa fragmentary perspective view .of 'a portion of one of the sashes, showing one' of the wedging 'members swung. to inoperative position.

Fig! 5 is a view similar toFig. 1-, but showing the wedge in operative position.

In the drawings I have used the reference character 10 to designate a conventional window frame formed .at its side edges with channels 11 in which upper and lower slidfing sashes 12, 13 of conventional construction are mounted. The upper edge of the lower sash carries a bevelled outwardly facing rail 14: adapted to mate with a bevelled inwardly facing rail 15 in the customary manner, so

that when the sashes are in normal closed position, the rails engage and prevent rattling of the sashes.

The present invention is more particularly concerned with the provision of wedging members 16 of general V-shape, each having one leg attached to a leaf 17 of a leaf hinge, I

the other leaf 18 of which may be screwed to the side frame bars of the inner face of the sash 12 as indicated at 19. The V- a shaped wedging member is of spring metal,

members 16, and tends to fold the wedging members, as best seen in Fig. 3, the lips 20 serving to positively limit the relative sliding movement of the sashes with the parts in the position of Fig. 3. The inherent-resiliency of the wedging member 16 will serve to prevent rattling of the sashes, and the lip 20 prevents the window from being entered byan intruder; inasmuch as it locks the sashes against relative movement to an extent which would permit an intruder to gain access.

For the purpose of washing the windows, I

it is merely-.necessa to swing the hinge plate 17 to the position of Fig.4,thereby carrying the wedge members out of the path of the rail 14.

Various changes .and alterations might be made in the general form and arrangement of parts described, without departing from the invention. Hence I do not wish to limit myself to the-details set forth, but shall consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of .the appended claims.

I claim- 1. A window wedge unit adapted to be attached to a sliding sash and including a leaf hinge, a V-shaped wedging member of spring metal having one end attached to one leaf of the hinge, and including a laterally 6' projecting lip at its other end.

2. The combination with a pair of sliding sashes, of wedging members secured to one sash and adapted for wedging engagement with the rail of the other sash, said wedging members including V-s'haped strips of spring 10 metal, and lips projecting from the free end of the strips for limiting the relative sliding movement of the sashes.
